Here is my buddy's rig. He emailed me those to post here for you guys.
1st pictured is from his forklift connectors. (to charge or power up trailer or in his case a winch). I use it on my dump truck to charge my dump trailer.

Was wondering why do you mulch so early in the year? and will the mulch you put down last the entire year or do you have to re-top it ? Normally i would not ask but you are only about 2 hr. away and people around here don't want it put down until about April. We will put our mulch out for our commercial customers end of next month, before mowing starts. Also Your works looks great
